First year teachers--In-service training; Teacher turnover; Teachers--Job satisfaction
Experts attribute the teacher shortage to an increase in population while others
cite the retirement of a critical mass of baby boomers who came into teaching in the mid
to late twentieth century. Other experts argue that the teaching shortage is...
Hepatitis C virus--Research; Interferon--Therapeutic use; Adenosylmethionine
Hepatitis C virus (HCV) infection is a major cause of chronic liver disease in the United States and is a huge burden on the US healthcare system. The FDA-approved traditional standard of care for HCV is pegylated interferon-alpha (lFNα) combined...
Wit and humor--Therapeutic use; Behavior therapy; Wit and humor--Psychological aspects
Objective: To evaluate the influence of positive affect inductions on daily and weekly Positive and Negative Affect Scales (PANAS) in a community setting. Methods: Humor messages were distributed to participants four times per day during a...
Complement, an early recognition system of innate immunity that senses local tissue damage and infection, cross-talks with and regulates other signaling systems, including Toll-like receptor (TLR) pathways. In the context of periodontitis,...
The lipid aldehydes, 4-hydroxy-2-nonenal (4-HNE) and propene-2-al (acrolein) are reactive α,β-unsaturated aldehydes generated during the peroxidation of lipids and are implicated in the pathogenesis of several oxidative-stress mediated diseases,...
Monophosphoryl Lipid A (MPLA), a derivative of LPS endotoxin, is a TLR4 agonist that displays as little as 0.1-1% as much toxicity as its parent molecule while retaining immunostimulatory properties. We discovered that MPLA activates a TRIF-biased...
Outerplanar graphs are planar graphs that have a plane embedding in which each vertex lies on the boundary of the exterior region. An outerplanar graph is maximal outerplanar if the graph obtained by adding an edge is not outerplanar. Maximal...
Chronic periodontitis is strongly associated with composition of the oral biofilm
occupying the gingival crevicular aspect of the tooth and its associated root. Some gram-negative,
"red complex" bacteria instigate periodontal bone loss in...
Arsenic--Physiological effect; Cardiovascular system--Diseases; Liver--Effect of arsenic on; Arsenic--Toxicology
Chronic arsenic exposure is associated with increased cardiovascular disease (CVD). Prenatal arsenic exposure at 49 ppm arsenic accelerates atherosclerosis underlying CVD in ApoE-/- mice, but the mechanism is unknown. This dissertation examines the...
The immune system is of profound importance for host survival due to its ability to clear many acquired diseases. In case of infections and cancer, disease arises due to under-performance of immune system. Whereas in autoimmunity and...
Quorum sensing (Microbiology); Cellular signal transduction; Bacterial genetics
Quorum sensing in the oral pathogen Aggregatibacter actinomycetemcomitans is dependent upon the soluble signaling molecule AI-2, but it is not known how the initial detection of AI-2 is coupled to the downstream regulation of gene expression that...
Epithelial Ovarian cancer (EOC) is the leading cause of gynecological cancer death in the USA. Recurrence rates are high after front-line platinum chemotherapy and most patients eventually die from platinum-resistant disease. P53 plays an important...
It has been shown that GSK3 β plays a critical role in the inflammation response by differentially regulating MyD88-dependent pro- and anti-inflammatory cytokines production in TLR4-stimulated innate immune cells. The work included in this...
This project investigated the effect of hypothermia on the monocyte response with the goal of understanding, which intracellular processes are affected by hypothermia leading to differences in cytokine secretion. A better understanding of the...
Embryonic development requires the orchestration of temporally precise genetic events that culminate in the formation of a complete organism. The molecular mechanisms responsible for ontogenesis are regulated by environmental and somatic factors in...
Dehydroepiandrosterone (DHEA) is a C-19 adrenal steroid and the most abundant circulating hormone in humans. Since circulating levels decline in late adulthood, treatment of humans with DHEA has been suggested to have beneficial health effects....
Among gynecological malignancies, carcinoma of the cervix is the leading cancer type worldwide. Conversely, vaginal tumors account for an incidence of approximately 1-2% of lower genital tract malignancies. Interestingly, the major shared risk...
Tobacco smoke is a strong and independent risk factor for several chronic systemic diseases and also increases susceptibility to a multitude of bacterial infections, including periodontal infections. Periodontitis is a chronic inflammatory disease...
Interactions between chemokines and their receptors are involved in organ- specific homing and propagation of metastatic breast cancer (BrCa) cells. BrCa cells express higher levels of CXCR4 and CXCR7 mRNA and cell surface protein, than normal...
4-hydroxy-2-nonenal (4-HNE) and propene-2-al (acrolein) are highly reactive á,â-unsaturated aldehydes. 4-HNE and acrolein are generated in vivo as products of lipid peroxidation. These aldehydes are implicated in the onset of several diseases...
